There's one available local to me for stupid-cheap for about FIVE HOURS. (It may just be relisted once the auction is over so still please give me a response even if it's more than 5 hours since I posted this.) Is there any reason people decide they don't like this amp? Bad reliability, bad tone, etc? Are the replacement models--I think the WT900??--substantially better? My main interests are: -- probably sounds better than class D, though class D is very good these days -- I ***think*** it probably sounds equally great at volume 0.1 as 5, unlike my PF-50T -- I plan on running 115 and 410 cabs off it, whereby the 410's sensitivity is like twice the 115. (twice is 6dB, in my case 5dB difference) So, it looks like the World Tour 800 has a balance for two outputs, so I can give more juice to the 115 if I want. Also, just the easiest way to A/B two cabs is to spin a balance knob. A distant second is that it also has a crossover frequency; I might possibly want to cross over between two cabs but I doubt it given that 210's can be flat down to 30Hz these days. -- I've heard that at least a decade ago, Eden World Tours were super reliable as well as great sound: "if you showed up at a festival and saw the back line had Eden bass gear you'd know the show would be fine" etc. -- I plan on using my Ampeg PF-50T as a pre-amp when I want the warming (or even distortion) and compression of POWER tubes working hard, plus transformer and rectifier nearly maxed out and on the point of sagging. I'd take it's aux out into the WT800's poweramp in or some such. Anyone have bad experience or know from the voltage ranges or something that this wouldn't work well? -- but when I don't need the tube sound I hope to just use it as is. Can anyone confirm it sounds fine even when turned down to conversational volume, e.g. late night goofing around when the baby's asleep? In a way even a 50W tube amp probably doesn't? -- I like the sweepable EQ If it matters, my current cab is an Eden D210XST. I'm getting a Glockenklang Uno Rock Art and Take Five Neo, I think. Eventually an Ampeg 810 for that 70s tone.
